Changelog & Upgrades

Updates to the Nabla Core API — including new features, fields, or endpoints — are released under a new dated version to ensure stability and predictability. This means your integration won’t be affected by these changes unless you explicitly opt into the newer version (see Targeting a specific version).

That said, some updates — like internal AI models improvements, bug fixes, or strictly non-breaking changes that don’t affect the schema or observable behavior — may be rolled out across all versions.

Below is a list of all available Core API versions, along with their associated changes.

2025-02-25

• Bilingual support has been added to transcription endpoints and Websocket.
  • In request bodies and WS config frame, speech_locale property has been removed and replaced by new speech_locales property, an array that can contain one or two distinct speech locales.

2025-01-07

• Add a new synchronous dictation from file upload endpoint.
• Add a new asynchronous dictation from file URL, with the ability to either:
  • poll the result through a polling endpoint;
  • or receive it via a webhook event.
    • Note: If you already have a webhook integration set up, make sure you go to the Developer Console and extend its set of enabled event types to include dictation related ones.
• Require endpoints host to specify a region, i.e. either us.api.nabla.com or eu.api.nabla.com, the generic api.nabla.com is not supported anymore.

2024-12-23

• Add a new transcription from file upload endpoint with the ability to poll the result through a polling endpoint.
• Change endpoints paths to start with either /v1/core/server or /v1/core/user.
• Change endpoints host to support for direct URL to a specific geographical region, e.g. us.api.nabla.com/* instead of just api.nabla.com/*.
• Remove or renamed endpoints (still supported on older versions for backward compatibility): /digest, /digest_async, /listen, /listen-ws, /listen_async, /generate_normalized_data, /generate_patient_instructions, /dot_phrases & /dot_phrases/{id}.

2024-04-22

• Add a new endpoint /generate_patient_instructions to generate a patient-friendly summary from an encounter.
• Add a new endpoint /generate_normalized_data to generate normalized data from a note, available on both the Server API and the User API.

• Add four new templates: GENERAL_MEDICINE_WCC, SOAP_WCC, GENERAL_MEDICINE_EMERGENCY, SOAP_EMERGENCY.
